  1. Vertical - cavity surface - emitting lasers ( vcsel ' s ) have distinct advantages over conventional edge emitting lasers, such as small divergence angle, single longitudinal mode operation and very low threshold current. they are especially suitable for making two - dimensional ( 2 - d ) arrays as well as vcsel ' s based integrate devices

    垂直腔面發射半導體激光器（ vcsel ）與傳統的邊發射半導體激光器相比，它具有發散角小、單縱模工作、非常低的閾值電流等優點，尤其它適於二維面陣集成和與其它光電子器件集成。
  2. Earthquake activity is confined to a rather shallow surface zone along such belts of divergence.

    地震活動就限制在沿著這種擴散帶的較淺的表面地帶上。
  3. It was well known that the main process of precipitation formation was collecting cloud water in the warm area and ice phase particles melting in the cold area. positive vertical velocity existed between 700hpa and 500hpa in the warm area and near surface in the cold area. wind convergence existed at the height of 700hpa, and divergence existed above and below the height of 700hpa

    通過對降水雲系的綜合研究，建立了河南省春季層狀雲降水概念模型：暖區降水主要通過雲水碰並形成，冷區降水機制以冰粒子融化等冷雲過程為主;暖區700一50ohpa通常有上升氣流，冷區上升氣流分佈在近地面附近: 700沖a存在風場的輻合，其上下則主要是輻散區;水汽主要集中在7o0hpa高度上，暖區水汽來自南、東南方向，冷區水汽以西南輸送為主;暖區位勢不穩定分佈在o 。
  4. The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller. the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution. for highly skewed propeller, the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface, which result easily in incorrect calculation results of velovity on blade surface, even in iteration divergence and calculation failure. a “ non - conventional grid ” is developed to acoid these problems. this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller. the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure. by sample calculating, the obtained results are satisfied the experimental data

    採用面元法預報大側斜螺旋槳水動力性能，螺旋槳表面及尾渦面離散為四邊形雙曲面元，每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言，槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元，這容易使槳葉表面速度的計算結果不正確，甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法，能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件
  5. The computation of three dimensional volume is converted into that of integral of closed surface, which is based on the divergence theory

    摘要利用散度定理將體積計算轉化為閉曲面上的積分，對曲面進行三角形網格剖分。
  6. The most variable regions between hi and b strain reside in vp2 and vp3 overlap region ( 319 - 470 ), which are supposedly exposed to the surface of the capsid. it is possible due to the selective pressure from host immune system. the largest divergence between the gpv - h1 and mdpv capsid polypeptides located between the start cordons of vp2 and vp3

    H1株與gpv - b株氨基酸的差異集中在vp2 、 vp3重疊區的319 - 470位之間，這與預期暴露于病毒最表面的區域相吻合，可能是宿主免疫篩選導致的變異； gpv - h1株和mdpv之間還存在另一高變區，位於vp2和vp3起始密碼子之間，這可能與兩病毒有不同宿主域相關。
